Patent GB-2100404-A (GB)
Title: Discharge lamps-combined lamp and socket
IPC: H01J5/56
Filed: 1982-06-04
Abstract: When discharged lamps are switched off after running for some time the voltage required to re-start them is very much higher than the voltage required when starting the lamp from cold. This can cause problems with arcing between lamp components. In a single ended discharge lamp and socket combination according to the invention this problem is catered for by the provision of a further insulating member placed between the lamp cap terminals. The further insulating member can be located within a slot formed in the lamp cap body or it can be formed as an extension of the lamp cap body fitting within a slot in the socket. <IMAGE>

Title: Automatic station finding for a consumer electronics receiver
Inventor: SCHROEDER WOLFGANG
IPC: H03J7/18
Filed: 1982-07-01
Abstract: An automatic station-finding arrangement consumer electronics receivers consists of three station-finding sections per finding process: namely a fast finding process in which a tuning voltage is continuously varied in one direction (curve 24 Figure 2), an opposite finding process in which the tuning voltage is backset by a predetermined amount  DELTA ??? (curve 25 Figure 2) and a slow, step-by-step finding process in which the tuning voltage is varied in successive digital steps (curve 26 Figure 2). The finding process is carried out with the aid of a tuning voltage generator circuit (2) guided by a reference input. A station-indicating signal (SSA) produced during the fast finding process upon passing through a tuning position of a tuner (1) at the signal output (18) thereof, turns off the fast finding process via a circuit 14 in a control arrangement (17), and turns on a finding process extending oppositely to the direction of the fast finding process. Thereupon, the control arrangement switches on the slow finding process and, simultaneously, the signal output (18) of the tuner (1) is switched over to the stop input (20) of a stop circuit (21). This method permits the fast station finding process to be carried out at such a high speed that the tuning to a station can be recognised, with the tuning arrangement, however, only being stopped upon passing over the received station in the course of the fast finding process. <IMAGE>

Patent GB-2105018-A (GB)
Title: Vertical shaft furnaces
Inventor: SHAW FRANCIS MICHAEL
IPC: F27B1/18
Filed: 1982-07-29
Abstract: A vertical shaft furnace installation includes a cupola (C) and gas- cleaning apparatus at the outlet of the cupola (C). In order to avoid heat damage to the gas cleaning equipment, diluent air may be added to the hot gases emerging from the cupola (C) in order to reduce their temperature, in particular at the end of the blow-down period. Should the temperature of the gases entering the gas cleaning equipment rise inordinately, a reduction in the blast of the furnace is arranged to occur; the reduction may be a progressive one with temperature increase or may be achieved in a single cut in the air- weight of the blast. Control of the blast reduction may be achieved by mechanical means or by a microprocessor or other electronically-controlled system. <IMAGE>

Title: A method of continuously producing compression moulded coal
Inventor: YOSHIDA HIROSHI
IPC: B30B11/26
Filed: 1982-10-11
Abstract: The invention relates to a method of producing compression moulded coal to be used for the block charging of coke ovens, wherein the raw coke is initially compression moulded, a part of said already compression moulded coal is caused to remain in the outlet of the moulding box while subsequent raw coal is charged into the box behind the coal in the outlet in order to be compression moulded, so that the latter compression moulded coal is combined with the former compression moulded coal whereby compression moulded coal is produced continuously. During the compression moulding, the already compression moulded coal may overcome the compression force applied to the subsequent compression moulded coal, due to the friction with the moulding box. Further application of pressure after the moulding operation will cause the compression moulded coal to be pushed out of the moulding box.

Title: Method and apparatus for strand delivery
Inventor: BROUWER CHARLES W
IPC: D03D47/30
Filed: 1980-08-05
Abstract: The invention, divided from 20607189, provides a method of supplying weft to a loom having a demand for finite lengths of weft at intervals. The weft is continuously advanced from a supply source for winding on to a first surface (310) toward one end of a second surface (320) for rewinding of the weft on the second surface. The loom withdraws the weft from an opposite end of said second surface toward said one end of said second surface, and halts withdrawal of the weft when said infinite length has been withdrawn from said opposite end of said second surface by said loom. This arrangement is especially suitable for use in weaving with shuttle-less looms of the air jet type. <IMAGE>
Patent GB-2133478-A (GB)
Title: Fuel injection pumps
Inventor: BOGLE PETER DEREK
IPC: F02M59/26
Filed: 1983-01-08
Abstract: A reciprocable plunger fuel injection pump has a plunger 12 slidable in a bore 9 in which is formed a pair of spaced ports 15, 32 communicating with a fuel supply gallery. The plunger has a spill groove 17 having an inclined edge 17A. In normal operation the plunger is angularly movable to adjust the amount of fuel supplied by the pump by virtue of the edge 17A co-operating with the port 15. During starting the plunger is moved to an extreme angular position in which the port 15 is uncovered later and therefore an excess of fuel is supplied. The plunger also has a recess 34 which can co-operate with the port 32 to delay delivery of fuel when the plunger is set to provide an excess of fuel. <IMAGE>

Title: Apparatus for measuring flow in an open channel
Inventor: MESCAL MICHAEL ASSUMPTA
IPC: G01F1/00
Filed: 1983-03-18
Abstract: Apparatus for measuring flow e.g. slurry in an open channel comprises a closed inclined tube 4 containing a flowmeter 7 through which all the flow from the open channel 1 is led. The flowmeter 7 is arranged below the level of the downstream side 3 of the open channel 1 so that the tube 4 is maintained full. When measuring the flow of a liquid containing settleable solids, the liquid is led into an inlet head chamber 10 and through the tube 4 which in this case is inclined upwardly from the inlet chamber 10 to an outlet chamber 11 for discharge to the downstream end 3 of the open channel. In another arrangement for measuring the flow of liquid containing floatable material, the tube 4 is inclined downwardly from an inlet chamber 10 to an outlet chamber 11 for return to the open channel 1. The flowmeter is a magnetic type. <IMAGE>

Title: Filtration method and apparatus
Inventor: TREANOR ANTHONY IGANTIUS JOHN
IPC: B01D24/12
Filed: 1983-04-11
Abstract: A liquid is filtered downwards through a bed 7 of granular material, and cleaning of the bed is conducted, when necessary, by upflow of wash water through orifices 9 and air through orifices 12 positioned mid-way between the orifices 9. An overflow 13 defines free water space 15 above the bed, and a baffle formed of elements 18, 19 and 20 shields the overflow. During cleaning the wash water and airflow upwardly at rates such that some granular filter material is entrained by upflowing air bubbles, but the baffle elements prevent such material from passing over the overflow. Elements 20 are perforated and allow the air bubbles to separate from the entrained filter material, which falls back to the bed. <IMAGE>

Title: Monitoring attention
Inventor: SWYER GERALD ISAAC MACDONALD
IPC: A61B5/18
Filed: 1984-04-18
Abstract: Attention or concentration is monitored by monitoring a correlated physiological parameter. Volar skin resistance is the parameter of choice. In a practical embodiment, a pair of electrodes (6) may be attached to the hand of a person, e.g. a long distance coach driver, and the volar skin resistance monitored by a suitable box (4) of electronics. If the resistance rises more than a predetermined amount, indicating the onset of sleep, a stimulus, e.g. an audible tone in a headset (8) may be emitted to alert the driver and increase his concentration. <IMAGE>
